I am on a committee that writes rules for a speed based college engineering design contest. http://speedfest.okstate.edu/Speedfe...les_Alpha.html

We are contemplating upping the engine limit and was wondering how much more power the OS .55AX has over the .46AX. The specs only show .01mor hp. I know manufacturer hp info is pretty much worthless so I was hoping to get input from people that have run both engines. Is the power increase noticeable and worth the change to the rules?

Thanks,

Dan
